no errors even though message says to read the output for more details
Python Env extension is not installed

@DonJayamanne does this only happen with Python venv created with version > 3.13?

This may be unrelated but wondering
if you have

  "python.experiments.optOutFrom": [
    "pythonTerminalEnvVarActivation"
  ],

on your settings.json or not
